Application filed January 29, 1919. Serial No. 273,821.

To all whom it may concern:

Be it known that I, WILLIAM ELMO CLARKE, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Inking- Pads, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of this invention are to overcome the objectionable feature of flooding the type of a stamp which is caused by an over supply of ink and to enable a uniform supply of ink to be maintained at all times, thereby preventing the smearing and consequent blurring of the stamped article.

A further and important object is to devise a pad which may be readily re-inked and further to devise a structure which simplifies the manufacture and reduces the cost.

The principal feature of the invention consists in feeding the ink to the inking surface from the ink container arranged beneath a solid block of material by means of a ribbon of textile fabric stretched around the block.

In the accompanying drawing Figure 1 is a longitudinal sectional View of an inking pad constructed according to this invention.

Fig. 2 is a perspective detail of the pad removed from the case and turned upside down showin the preferred manner of arrangement of the inking pad, ribbon and block.

Referring to the accompanying drawings, the block -1 is preferably a piece of wood which is treated in a suitable manner to make it impervious to the action of the moisture and acids of the ink. A ribbon 2 of a light close woven textile fabric extends completely over the top surface of the block and the ends are suitably cemented to the 7 under surface of the block at points adjacent to the center. The ends of the ribbon may be overlapped if desired, but it is preferable to cement the surface of the block transversely across the center and the ends 3 of the ribbon are laid down upon the cement leaving a central strip 4 between the ends exposing the cement.

A pad of felt or other suitable absorbent material 5 is then placed upon the block and the cement strip 4 securely holds the pad in place.

The whole pad as thus constructed is ready to be placed in the metal case 6.

Before placing the pad in the case, the felt pad 5 is saturated with the ink and it is then placed in position with this felt pad upon the bottom of the case, as shown in Fig. 1.

The capillary attraction causes the ink to travel from the pad around the textile ribbon and the stamping surface is kept constantly supplied with ink. As the wood is non-absorbent it will not warp and presents a flat even surface for the type and as all the ink is supplied from underneath by capillary attraction through the ribbon, there can never be any surplus ink upon the stampin surface.

It will be readily understood that a pad such as described will continue to feed ink practically indefinitely or until the felt pad becomes practically dried out, as the pressure of applying stamp to the upper surface will continue tosqueeze the ink from the inner texture of the pad 5 every time the pad is struck.

An inking pad such as described greatly simplifies the manufacture, as the parts are all assembled in dry form, that is to say no ink is applied untilthe pad is completed and ready to be placed in its case. This eliminates the necessity of the operator wearing rubber gloves or requiring the use of special chemicals to remove the stains from their fingers which is necessary in making the ordinary forms of stamp pads as the fabrics fie saturated with ink before being assemed. r

The textile materials used are reduced to the minimum and a very desirable commercial result is obtained.

What I claim as my invention is 1. An inking pad comprising a block, a cover of textile material extending over the top and around the edges of said block, and an absorbent pad forming an ink container arranged beneath said block.

2.. An ink pad comprising a block having a flat top surface, a cover of textile material stretched over said fiat top and around the edges and secured to the underside of said block an ink containing pad of absorbent material secured to the underside of said block and contacting with the said textile cover.

3. An ink pad comprising a Wood block rendered impervious to the ink to be used and having a fiat top surface, a cover of textile material stretched over the top of said block and having 1ts dges secured to the underside at points adjacent to the center a 10 WILLIAM ELMO CLARKE.
